WHY ULTRASOUND MONEY IS DEAD WITHOUT MAINNET USERS

Summary from the TLDR Crypto newsletter

L2s can play games by posting data to the mainnet, using blobs when it is cheap and slowing their posting frequency when it is expensive. During a previous period of high fees, Scroll stopped posting altogether while Taiko slowed its page. Mainnet power users and builders are critical to supporting ETH as a utility token, though L2s using it as their primary form of currency improves its monetary premium.
